Answer:
see the explanation
Step-by-step explanation:
we have
[tex]3:\frac{3}{4}[/tex]
Multiply in cross
[tex]\frac{3*4}{3}=\frac{12}{3}=4[/tex]
Jane got 2 1/4 because she multiplied 3 by 3/4 instead of dividing 3 by 3/4.
so
[tex]3(\frac{3}{4})=\frac{9}{4}= \frac{8}{4}+\frac{1}{4}=2\frac{1}{4}[/tex]
